This form calculates which transits of the 1039 known transiting exoplanets are observable from a given location at a given time. Specify a time window, an observing location (either an observatory from the list or choose "Enter latitude/longitude" at the end of the list), and optionally any filters (e.g. minimum transit depth or elevation). The output includes transit time and elevation, and links to further information about each object, including finding charts and airmass plots. ...

... This paper describes the main algorithms used by the Einstein Level One processing to create the exposure masks and the background maps for Einstein IPC images, and how these algorithms were recreated in the IRAF environment.
